Hey Muzzy, ask me why I went back to Aluminum. Your setup would most likely be X7 2312 with 50gr hot-tips and feathers on the rear end. Come to think of it you might want vanes on the back and little point weight just to get legal. I've been shooting 2212's, 27" at 60# and they only weigh 309gr. OK, so they're not as durable as carbon. But neither are my shoulders. I've had guys tell me they'd pull mine all day long. And that's without any lube on them.
Just my experience but most of the Carbon Express are the worst to pull.
