Oh, Ok......the current I/C is only .350" off the ground, and not 3.50"......wow that is low.
Try #1 for starters because of the three it will be a decent jump in I/C height, but not as excessive as the other two. Don't be surprised if you end up having to tighten up the rear extension valving up closer to the full tight range of say 4 to 7 back from full tight. The rear compression could probably stay around the 50 - 60% tight range depending on how much air you run & how hard it ends up hitting the wheelie bars next time out.
Might also think about playing with the strut extension valving as well. You could try a hit at 1/4, 1/2, & 3/4 tight to see if theres any noticable difference with each course jump in adjustment. Do your struts adjuster nuts have 3 full 360* rotations from full-loose to full-tight, or is it more like 2.85 to 2.90 full rotations?
[Edit] never mind, I was thinking about full turns on Lamb struts.
