So many people with the hand way back on the butt of the cue lmao, these same people spend hours searching for a cue with a 19" balance point, give or take, like it matters. While your at it, you can throw weight out the window too if your hand is on the butt cap side of the cue. Some of the best players in the world played with SW cues yrs ago, and the norm was close too 20oz, if you hold the cue on the designed spot for a proper balance, a 20oz cue will feel light. That was the whole idea of a 'custom' cue! Has nothing to do with the inlays, and flash, but it showed a cue that was measured/balanced for you. A custom job.....
You should measure your grip hand position from the bottom of the cue, then figure out what length cue you need, and were to balance that cue.
So if your wing span is short you use a 57" if your tall with a wide wing span, you make a 59-61+++ cue and tell the cue maker you want it to balance at this point, and close behind that, is were you train your grip hand to fall 'most' of the time (it will be behind the true balance point in most cases these days. You need to figure out how much with the cue maker.)
So if you want a cue with a little forward balance......
Find your grip hand position measure this from the butt
The cue maker then needs to have a good idea what length the cue needs to be with the wood used, to nail the balance point so you grip it on the right spot. If you tell the cue maker you want a little forward balance on the cue, the cue has to be adjusted in length too allow your grip hand to fall on the adjusted spot too assure a forward balance.
Same with a neural balance or butt heavy balance. If you grip a neutral cue, the the weight should be equal front to back, so if the cue rests on your pointer finger it balances. If you want a little forward balance the cue should fall slow forward when balanced on the pointer finger. Sorry, but if your 'custom cue' doesn't balance right were you grip the cue on most shots, then its not a custom. Hate to say.......If you grip on some dumb spot like the butt cap, and tell people its a forward balance, LMAO well no kidding! Grab it were its supposed to be gripped and find out then......after that, sell it and have one measured/balanced to you...... then the length and weight mean something.
Also, the thickness of the handle in the grip area......for your hand and grip style.... comes into play on a 'true' custom cue.
When all this works, a little heaver cue feels light, and you can get rid of all the cue deadening core, and play with solid wood, which gives a much better hit, around 19.5-20oz IMHO. Sw cues play real good, no core.......Core is a short cut that cuts out the sound of a cue, and makes it sound dead (most of the time). IMHO
So really, there is no magic pill' if you want a soild cue, you need soild wood, so that jacks the weight up some to around 19.5 (no core). If you have a true custom made, it will be balanced to you only.......The added or reduced length is just to find the proper balance point for you. At this time, if you nail it all right, and keep your grip hand on the right spot, the 19.5 cue will feel light.
There is exceptions of course. But the rule of thumb was two fingers forward of wrap for balance point. Really, how much stroke do you need playing on all this new cloth? If you need to throw off a balance point and make a cue feel more heavy for 4" of extra stroke, you prob. should be looking to fix your cue-ball contact points. Keep the cue balanced right, with a proper length for you, and work on not needing to use a extra 4" to move a cue-ball around on these super fast cloths. I wont get into the fact i'm a firm believer that long strokes are for show, and people that needed to make money to eat, 24/7, knew that a short compact stroke, staying middle cue ball much as possible, equaled food,and people that needed to show a powerful long stroke unless they were named 'hook' were probley making the game harder then it needed to be........
