I've got a dozen of the TR Crush series shafts. Honestly, I cut 'em to length and installed the inserts/outserts but find it pretty darn hard to get excited about actually shooting 'em? Talk about outdtaed technology..... we all used these skinny carbons with outserts back in the late 80's before they faded away and were re[placed by the more modern technology. I just can't see myself ever wanting to set down my trusted CX Aramid KV's and Maximas for these TR shafts.
