When buying a Speedy 25 or 30....Do you buy depending on your size? Meaning height and build? I have the cerise which is a 25, and a mono speedy which is 30...I'm thinking of purchasing another speedy and was interested what you base your Speedy size decision on? How much you carry? OR If the 25/30 is in proportion with your body size? Which is most important in factoring your decision? I put the things I usually carry in my cerise and it all fits...but then I think it looks too small for me (frame-wise) in proportion to me. (and I can't fit a magazine inside..) Then I put everything in my mono 30 and everything fits plus my magazine..and it looks much better with my frame. Which is good...then there's the sagging issue...Ugh...but a mag on the bottom should fixes that somewhat. Also I noticed when I put all my things in the 25 it's just about full 3/4 of the way. In the 30 it's a lil less than 1/2 the way full..so I have plenty more room for things..., So technically the 25 would be fine for what I carry...but it doesn't look in proportion to my frame. Looks TOO small!! Kinda funny. Do any of you buy the 30 knowing you don't have a ton to fill it up, but get that size cuz it fits your frame better? Btw, I do like that fact if I need to throw more things in my 30 there's room. So that's a plus. Should I get the 25 being there should be less sag (so I've heard), but then the bag will be too sm. for my frame and not fit a mag. OR the 30 which looks a lot better on me, fits a mag...but then I'll have more sag than the 25, but not overly saggy cuz of the mag on the bottom? What would you do? TIA!
