Need help on weights for Dopp kits and Purses

[SilverForgeStudio]

So I will be trying to cobble together some Dopp kits for the fellows in the family this year- and the ladies will be getting bags... Hoping to get some answers for a couple of bag and Dopp related questions:

1- I have 9-10 oz veg tan but this is way too stiff to think about turning right-side out... Is 4-5 oz the standard for Dopp kits?

2- I want the messenger bag(s) to take a bit of abuse so Im looking at 5-6 oz... is this getting into bulky territory (having never done this- I know it is ambitious but I have looked a lot of places and my search-karma produces no results about weights of leathers discussed for what type of bags vs. abuse)

3- Would Horween brown be overkill?

I truly appreciate the help and assistance- like I said in the first posting- hopefully you guys can get a chuckle out of my noob ideas and nudge me in the right direction(s)

Be safe and as always- At Peace!
