I’d suggest demo’ing as many bike as possible to see what you like and dislike.. Yes that same old advise, trotted out constantly.
BUT.. we don’t know what you like. I like single pivot suspension, and even though I know 4 bar is way more efficient, it just feels mushy to me & I hate it. Slack angle or XC steepness, I’d never suggest a XC bike to my m8’s, but one went out and bought one and loves it.. The “demo day” season starts March-ish, this give you time to see what you think you’d like, the ground will dry up (hopefully) making a test ride more worthwhile (what the point in slogging around in the mud trying to find the feel of the bike) & give you the opportunity to test bikes you might not have considered or have written off. I test rode on bike last year, to see how good the other bikes on my “potential purchase” list were in comparison.. I came away wanting the supposedly rubbish bike..
Unless of course your talking 2nd hand, which is another barrel of fish. Which re-reading your post, is probably where your heading. I think you need to dump the 100mm forks, something like the SC Superlight/Giant Trance or even the Grapil really need 120mm to make it “fun”, unless they can have your fokrs travel adjusted upwards.
