had 300c, did not replace it when i went to 15 lbs, was great at times, no so great other times, hard to describe, but not a consistent reaction if that makes any sense.
have 300a & 300t currently
300t - drilled pin down and weight hole on PAP, was great for NATS last year and awesome on short sport pattern, takes to surface changes well.
300a - have a bit of a trick drill on it, 2" pin-pap, does not over react, very smooth at the breakpoint. - also takes to surface changes well.
easily could have another 300t with a pin up drilling
300t on this years NATS team pattern goes straight.......
did not try it yet on minors pattern
mostly for lighter volumes
can be drilled for either sport or THS
300a and 300t do compliment each other, 300a will go further dowen the lane before it starts to turn over.
300t has an earlier, more predictable motion IMO
