warped bag need new one, lookin for suggestions

[Geronimo]

From the footage on the few vids ive made thus far Ive seen that my Promex black 7x10< i swear its WAY Smaller> is warped its not lookin nice now that i see the lopsidedness to it. The bags had a lot of use so no biggie now i have to retire it. So Im lookin for advice and reviewed bags so i get 2 solid FAST MEDIUM sided bags, I prefer 6x9 -7x10 size bags med small to med size. the pro mex seems to have a slower rebound compared to my everlast black/yellow small 5x8 or w/e it is. Was wondering about the Title Gyro bag on sale for 29.99 seemed like a good bag but none the less lookin for some opinions / reviews, or FAVORITES =). So far Ive owned 2 everlast bags and that lopsided Promex.

You can't go wrong with any of the title brand bags (http://store.titleboxing.com/speed-bags-platforms.html), fighting pro sports or Rival. All good reliable bags.

The Everlast red and blue 8x5 bags are still on sale on the clear out products page on the title site, I have 4 of them and so far no cracks in the leather, and one of them has even taken a few beatings from my father who was once a golden gloves champ, and it's still in great shape, and for 19.99 you can't beat it Everlast 8x5 speed bags (http://store.titleboxing.com/titleboxing-everlast-speed-bags-co.html)
