Newly diagnosed, and no hypos so far, but on my current regime I've been bumping along close to 4 and dropped down to just below a few times so had to correct for driving. Havent used them yet, but I'm carrying mini packets of haribos just in case.
My favourites to keep me level and stop me dropping (which have carried over from my pre-diabetes days) include 9-bars and NAKD or TREK bars.
The 9-bars are seeds held together in honey/cane sugar syrup. The NAKD bars are either dates/raisins/nuts and natural flavourings or the same but with added oats and/or proteins. I find they have soem quick action but also a good slow release as well. ALways found them good on the bike and while running, you can break a bit off and put the rest back in your pocket.

I buy them by the case, cheaper, no P&P
