Personally, I'd say that a sub-24 SDW100 should get you through WS100 under the cut-off, (30 hours?)
I did NDW100 in 23:45 and then The Bear 100 which is a lot tougher than WS100 in 28:30 and I could have easily gone a couple of hours quicker if I'd really wanted to... I've also run the SDW trail solo in 26-ish hours for comparison.
The trouble with WS100 is getting in! The odds are very low for first-timers, I applied twice and never got in either attempt. Dragon's Back in 2015 so am out of the running next year.
I say if you have a qualifier go for it, just train for those downhills
