I’m running my Mk3 Soul with Float RLC FIT 120’s…but wish I had opted for Reba instead due to the ease of maintenance (still really good forks though and really tuneable).
I did run 110/140 Talas’ but kept forgetting to switch the settings for climbing and descending…and it didn’t handle quite so well in either setting compared to 120’s.
I was running a full 2×10 SLX groupset bar a XT cassette (helps with lessing the scoring) and KMC X10L chain, but have moved to 1×10 NW set up.
There were some new XT/SLX cranks in the classifieds for a good price. You could always try ze germans which is where I got my stuff from and if you pay over a certain amount they don’t charge for postage either.
I know you’re on a budget but if you have MK3 frame then get a dropper and if going 10 speed a clutch mech is a must…two best inventions for bikes IMO…apart from 650b obviously 😉
