Good luck with getting on the pump, Tom! I bet you will find it easier on trips and climbs. I've been on a pump for 15 years now and you couldn't pay me to switch back. It makes things sooo much easier and a lot more convenient. Not to mention only one "injection" every three days means less supplies to carry, even with back-ups. I hope all goes well and you get that pump soon!
