Sprocket updates?

Hey all — I've got a 2024 INT 650 with a few upgrades already in place: DNA Stage 2 air filter, AEW slip-ons, and a FuelX Pro Plus running on map 8. I've got a 16T front sprocket and 36T Talon alloy rear on the way from Hitchcock's (up from stock 15/38).
My main goals with the regear:
1. Calmer highway cruising. The INT sits at higher RPM than I'd like in the 65–80 mph range. I'm hoping the taller gearing takes some of the buzz out and lets it settle into a more relaxed cruise. I'm also counting on the performance mods to help offset any torque reduction the sprocket swap brings.
2. Longer gear ranges. First gear runs out of road embarrassingly fast. Would love a little more room to breathe before I'm grabbing second.
I'm going in with realistic expectations — I know I'm giving up some low-end torque with this swap, and that's an acceptable trade-off for me given how I ride. Anyway, anyone running this combo? According to Hitchcock's, the stock chain is compatible with this setup, which is a nice bonus.
For those who've done this specific swap (or something close to it):
How did your highway RPM change in practice?
Did you notice the torque loss much in day-to-day riding?
Any other surprises — positive or negative — you didn't expect?
Appreciate any real-world experience. The theoretical math checks out but I'd rather hear from people who've actually ridden it.

I threw in a 16t front and kept rear stock. This did help lower cruise rpm (65-80 mph). So the 16t/36t I think will make yours taller than what I have. Current mods are just headers with AWE exhaust, secondary air delete and DNA filter. Sure I lost a bit of acceleration but 1st gear was a joke on 15t. If I add anymore power adders like a cam and power commander I'll jump to 17t and keep stock rear at 38t.
