Remember, there is no such thing as a no squirt/deflection shaft. There are just shafts of varying degrees of squirt/deflection.
You're pocketing balls better with a regular shaft for one night may well have been a result of better focus, knowing you were playing with a different non-familiar cue. Hell maybe it was the butt that was the difference. Is yours solid & the borrowed one spliced?
I hope you get my point. One night does not a career make.
Do you have a regular shaft for your cue? If so, do some experimantation. If not you can generally get a new one off of ebay for under $50.00.
I will say this I had & now have inherited back a 314 Cat that was juiced, sanded down, that I can not play with due to the fact that it will out swerve the squirt on long full table shots. It's awesome in close quarters but too unpredictable on the long ones where one usually needs more 'help'.
Also remember, it's what ever is best for you, whether it be a high end, high cost, LD or a broom stick.
Good Luck in making your final determination.
