Currently running XT 11-36 10 speed cassette with 26-38 chainrings on 27.5 wheels. Finding I need something a little easier for climbing (yeah, I'm unfit!) so looking at the following combinations:
Change to a 24-38 front and keep the existing cassette (cheapest and easiest option) but wondering how much benefit I might feel with this over the existing setup? I'm not after that much difference TBH, but wondering if I'll feel it?
Change to a 40t expansion cog on the rear, losing something in the middle, will need new chain as well so costs a little more. Think I'll get more in the way if a crawler gear, but unsure how much this will affect shifting performance?
Change to a 10 speed 11-40 (such as a sun race) cassette, most expensive, but possibly preserves performance, unsure though as can't seem to find much in the way of testing/reviews for this type of cassette?
Any experiences as to what might be best?

Bung all your possibilities into a calculator to compare them:

There's very little difference between a 24:36 and a 26:40
