I have a pair of 10 oz cleto safetec fight gloves. To be honest they are more well padded on the knuckles than even my winning g 10oz fight gloves. But overall I think the winnings are better because of ideal fit and thumb postition.
I belive the amateur gloves you speak of come as two pair red and blue. And are a velcro version of the safetec fight gloves. They should be fine for mitts and some light bag work. I would recomend Winning for sparring, or more economical - Ring to cage's clone the "C-17".
Largely people frown on training with fight gloves. But I do it myself. Fight gloves are useually better quality than regular gloves. And they are made to accommodate a pro fight wrap. (But I would recommend a pro training wrap). Everyone is different and some people have hand problems and need the extra padding of training gloves.
If your planning on fighting on a amateur level . I would find out what gloves you will be using so you can train in those gloves on some level, even if it'st just mitts.
Cheers.
