Firstly, nice name.
Secondly, you'll want a Hope pro2T really - That guide was written 7 years ago and there have been lots of updates since.
The easiest option would be to buy a second hand 26" wheel off here. A pro2T on some sort of trials rim (Not sure on spacing on a T-Raptor, not sure you can fit a 47mm wide rim in, might have to stick with a 38mm wide with holes) would be like £100ish. Or buy the hub second hand (£50ish), new spokes (£10ish) and pay someone to build it onto your old rim (£15ish)/ do it yourself.
