If you want sparring gloves and cost is not an issue then go with the Reyes or Grant.....I personally like the reyes the best, more support in the wrist area because there is more padding and a longer cuff....the foam also seems more compressed, the fit forms to your hand better because of this.....if you have a place to try these on do it.
If you want a similar style for less $$ go with the ringside Mexican style sparring gloves, they have alot of styles but the mexican style is basically copied from the reyes style....do not go with the international style...IMHO they suck ass.....ringside contender stuff is cheaper but it definatly shows in quality.
