Thanks guys for your in puts. So would you say buy the longer fd+ set or regular length? Can't buy both but I use the cheater bar or add a wrench technique when I need more leverage? Obviously you can't just cut off a pice or shorten a wrench with much ease
I use stubby ratchet wrenches when doing interior work when I can't get on a screw with a socket or screwdriver and they are too tight to loosen by hand. In that case, I need very little leverage, just something quick and easy to help me remove a screw. I have Snap On, but I think I'd be happy with any stubby ratchet wrench.
The scenario above almost never happens under the car or under the hood (for me). Most times, I can ratchet bolts all the way out. Maybe this is more than you wanted to know, but in my experience, having a ratchet with low back drag that will allow you to ratchet something out far enough to finish the job with your fingers is a big deal. Only the best ratchets can do this. And they have to be greased correctly etc. Otherwise, that's when guys reach for some other tool, start talking about the knurling on their extensions etc. These are solutions to problems a good ratchet solves. We don't talk enough about back drag. Low back drag keeps a one handed job one handed.
So fundamentally, I don't see much use for short wrenches.
Snap On's FD+ are already some of the longest combos on the market. I think they are the longest regular length?? (I think Armstrong's XL are comparable in length to Snap On XLs but not quality). If you need a long open end wrench, buy the Snap On XL or Armstrong XL.
Otherwise, just about every mechanic I know loves the Snap On high performance DBE wrenches (XDH...) which are inches longer than even the longest combo.
I use open ends infrequently - like only when I have no other option. So if I'm reaching for a box end wrench to crack something free I pick the longest model in the drawer. Therefore, I would start with a set of those high performance DBE. 99% of the time I use a combo, I'm using the box end. And the XDH wrenches are longer and better in just about every measurable way.
Once you have those, then think about combos. I would just get std length combos. But be sure to do some homework. Snap On's regular length are longer than Stahlwile or SK's long pattern. They are way longer than their competitors regular length.
