Rev’s can be dropped to 140 or 130 if needed. Velvet RL2 DLA do 110-140 as do Rock Shox Sektor RL Dual coil (but these are on the heavier side 2000g.
Most folks on here reckon 120 is the best for a Soul, but there are quite a few that run Talas forks or Revs at 130.
I got a pair of new uncut tapered Fox Float 32 Factory RLC FIT 120’s from someone on here for £400 for my Soul build.
CRC are doing white Fox 120 Terralogic RLC FIT tapered for £489 if you can afford them and live without Kashima…mine don’t.
What colour frame are you going for?
Oh there is also a Soul review with 120 and 140 forks in What Mountain bike out this month on the 23 Oct…have a read in WH Smiths.
