Swap the stem out if it feels too long. Don't forget stem rise in the equation.

I think one of the best tools to dial in the best length and rise is via one of thus adjustable stem doo-hickies like the Size-O-Matic from Salsa.

So I would suggest checking with an LBS or two in town to see if they have one of those Salsa Size-O-Matics that you can mount on your bike and find out what feels best. I've used it a few times to order some stems.

If you can't find one with a Size-O-Matic or similar device, find an LBS that has a box of used stems you can try out so you can see which length - 100mm, 90mm and 80mm, etc... - feels like. Or maybe they will sell you one of those stems (or a couple) with the idea you would be bringing back the one(s) that didn't work for a refund.

My experience in swapping out stems on 29"ers is that shorter ones can quicken up the steering a bit, but also can lead to the front wheel flipping and flopping more through those turns than a longer stem. You quickly adjust as a rider no matter what length, but I think you will notice a difference dropping down 10 - 20mm right off the bat and find a length and feel that works best for you. Certainly a stem in the 90-100mm length is in the sweet spot for a 29"er. The only way to find out is to try some various sizes and angles out before settling in on a final choice.

Of course, the other choice would be to keep your 110mm stem and get a handlebar with more sweep in the 12 - 17 degree range.

It's all plumbing and you can dial in a better fit if you feel too stretched out at the moment.
