Still new to this and I keep seeing the word mod thrown around. What exactly is a mod? And it seems the general consensus is that bigger is better. Am I in the minority that I like the slim look of the smaller batteries? I currently have an itastevv and I don't see myself wanting to go with anything larger. I like the feminine look of it (not saying men that have one are feminine but compared to the big honkers out there it looks more svelte). It does everything I need it to do (seems to have more features than most other ones I see out there) and with being able to use it while it charges I don't have the need for a bigger battery. I know if I found something I enjoy I should stick with it but am I really missing out on something by not getting "bigger and better"? Is what I have considered to be good in the eyes of the more experienced? Again I know it comes down to personal preference but I would like some input please.
