Last year at Six Gap I had my 53/39 with a 12/28 and rode the 103 miles 11,000+' of climbing without major issue on 10 days of notice. My 39/28 is a 36.6 and your 34/28 would be a 31.9 compared to your current 34/25 at 35.8. If your rear can handle it, you might want a 32 for extra cushion if in doubt 34/32 at 28. For as short as it is, Sugarloaf is a good climb for Florida Flatlanders especially at the almost end of the Horrible Hundred and the % is the cause of that compared to the mostly gradual climbing at Six Gap.

If in doubt, have a low-low just in case. Doesn't mean you have to use it.

Friends with LBS just got a house a couple miles from the high school and it sleeps 20. Wife and I are staying next to McDonald's at Motel Inn, also a couple miles from the HS.
