Can anyone offer advice where to get a boardbag to suit a 10'1" x 26' longboard sup. Standard bags are to big & longboard bags to narrow.

Reasonably cheap, custom bags that'll work perfectly. Socks, 5mm bags, 10mm travel bags...
Sunova's bags look great, but don't know if they do a size to suit.
Otherwise you could always take your existing bag to a machinist to trim, re-sew seams...
Balin made me an excellent board bag (for a race board though...) as well for a great price - super nice people to deal with too...
