Sounds good.
I put my 36 Talas on mine recently when I was heading up to Scotland and the Froggy was out of action. At 130mm it was good for singletrack, trail centres etc. and the 160mm setting was quite handy on steep bits. Too floppy otherwise though.
Rev back on now though and I think I'm happier with that at 140mm or 150mm.
If you've got XT brakes already I'd be tempted to put those on and flog the RXs new. I persevered with the RXs for a bit, but have resorted to my trusty old XTs now.
Look forward to seeing the pics.
