I have a fairly new mono speedy 30. I just purchased a 35. I don't need both...right? Should I sell the 30 and use the money for a new bag. I'm just wondering if I will regret it. I don't know if I will find the 35 too big later on. Right now, its new and I'm liking it...but who knows how I'm gonna feel later one. What's your thoughts??? Thanks much
