I had the LFX18A1 Shrai from another bike, so it was a no brainer to put on the VFR. I am blessed to be living in a warm clime, but winter mornings do get down into the 30's. I've never have any problems starting first click. No the weight savings probably isn't noticeable by itself, but add it up with the savings on replacing the stock muffler, and it's quite a bit. Overall, I'm happy with the Shorai. Compared to VFR's stock YUASA YTZ14S, which costs over $100, the Shorai isn't all that expensive. We don't have the problem of "winter storage" here, but I have several bikes, and there isn't enoug riding days in the week to love them all. So I normally install a charger lead on every bike I own. Since this Shorai has its own charge port, I didn't bother with a pig tail. Instead, I hook up the balance charger every 1-2 months to balance the cells. Regular chargers would work fine, as long as they do not have a desulfating mode that outputs more than 14.4V.
