I'm a BHE user. Always have been and always will be.A word about sidespin. I've had this come up quite a bit with different students the last month so I felt a general public service announcement was in order.
There are different approaches but the one I support by far is FEEL. The two other approaches I've seen are: 1) People struggling with the idea of back hand English, and 2) People that give up on sidespin because they can't stomach the short term impact to their pocketing.
Listen, I know a few people use BHE, but they are in a very small minority. The problem I have is it doesn't solve the need for feel. On a sidespin shot the cue ball deflects off the tip, curves back towards the shot line en route, then throws the object ball upon contact. How much depends entirely on swing speed and table conditions. So while a system can get you in the right general area, there is no escaping that you will need to develop a feel to make it work.
As for giving up on sidespin, this is a huge blunder I've seen so many times this year I am shocked. How can you spend years and decades playing a beautiful game like pool and resign yourself to slugging balls around with center-ball hits, shrugging off the fact you'll only be live to run about 50% of the tables where a limited tool box will suffice, and seeing only incremental improvement for half a lifetime? Why?
Sidespin isn't that hard. When you get down on the shot your tip should be where you want to strike the cue ball and you should be on the shot line you feel that already accounts for deflection/swerve/throw. When you're down you can fine tune the tip and aim slightly. If it's more than a fine tune rise up, air stroke, and reset.
From there all you have to do to master sidespin is miss 1,000 shots. That's it. Take my thousand miss challenge. Shoot with extreme sidespin on a variety of shots until you miss 33 times, and do that every day for a month. Ta-da. You can now make balls with sidespin and there is a new dimension and future for your pool game.
Don't buy into the whole 'pros stick to one tip from center'. That is absurd. Every strong player spins the ball like crazy unless they are playing straight pool exactly and their cue ball isn't moving more than 6-18" per shot. And for the love of all that is holy don't try to control all of this analytically. It can't be controlled consciously, you need to delegate this to your subconscious and give it the thousand shots worth of data for your inner computer to figure it out. I've spent time at the table with a lot of great players and none of them are making manual adjustments at the table. They just picture the shot they want to execute and feel it on in. If you can't do that yet then start missing and you'll be there before you know it.
Having said that, I liked your post. It is good info for any student that is struggling with side spin.
