sure everyone experiences squirt and not everyone misses. But as you said in the your first reply here, consistency is key. You still get squirt (just less) even with LD cues. so switching back and forth just leaves you with having to adjust your game for how much squirt to expect back and forth. I think its particularly an even worse problem as generally, the shots you are shooting with the most english - most likely for squirt correction to be meaningful - generally are either lower odds shots or shots where making position on the next ball is extra difficult. I can more easily shift anywhere between 17-22 oz of cue weight so long as the shaft stays the same as it just affects speed, not direction of motion.
I agree. The OP was asking if anyone 'can' switch between shafts. My take is the same as everyone else's here I think in that yes people can but that adjusting to the different amounts of squirt is required.
I think the only difference is that most people here are focusing on why it is a bad idea (and I agree) while I was trying to focus the obstacle to overcome if someone is so in love with the idea of switching shafts that they just had to do it.
Something that caught my eye on the OP's post was the idea of playing with whatever shaft "feels best that day". I might be weird but I love my cue/shaft and have played exclusively with it for the last few years. I've tried to play some with my old stick recently and it just feels wrong at this point though I loved that thing for 15+ years. I don't see how different cues could feel right on different days unless someone just likes the variety and doesn't worry as much about the feel of the hit, etc. Am I weird in thinking/feeling this way or maybe am I just not at a level of skill where I can shift between cues?
