Best gloves for incidental DMSO exposure?

In my new(ish) work, we got a new (for this place) chemical in, in DMSO solution. Reading the MSDS I got with the solution, I read the gloves that should be worn for DMSO are butyl OR nitrile. I worked with this chemical in another lab, and we always wore nitrile gloves (not even double-gloved!), but my safety manager is saying butyl.
From what I understand, butyl gloves are recommended for extended contact - as DMSO can eat through nitrile in about five minutes - but what we're working with will be 10uL of the chemical, 2uL at a time, each day it's used, and it will only be used for 4 days out of the entire year.
I'd like to bring something to the table besides butyl gloves for two reasons:
1) their bulk - I'm worried using butyl gloves to hold 0.2uL tubes will cause more, not fewer accidents and "spills" (but I've never used butyl gloves and a micropipette before, so I'm not sure).
2) their cost - outfitting the lab with the proper quantity of butyl gloves would take up an unreasonable proportion of our year's budget, considering how often we will use the chemical.
I am going to suggest double-nitrile gloving it, (some combinations of 4 and/or 8mils) but does anyone have anything else that they use?
New gloves brands come out and I'm never sure whether the "X-TRA!" means extra protection or extra comfort....
Does anyone use butyl gloves for merely incidental DMSO exposure? Does anyone use nitrile gloves for heavy DMSO exposure?
Or should I just tell him that since nitrile gloves are allowed in the MSDS he needs to get over it (well, say it through my lab assistant, who will be more diplomatic)?
(if you're curious, the chemical in the DMSO is SYBR Green I, directly loaded into the DNA samples.... which we got because he was always upset about the EtBr....which I don't like either, honestly, haha)
