central american kinkajou wanted or info appreciated

im looking for another kinkajou but im looking for a slightly larger subspecies than i already have. it seems that everyone has the smallest, south american type and i was looking for ,if not the largest type, maybe something slightly larger than what i see being sold everywhere. can someone who knows more than me describe the differenances other than size? and perhaps direct me to a seller who has an male that will be around 5-8 lbs? im looking for a baby or young adult, and i can wait if someone has a larger type breeding pair. id also love to hear replies from anyone who currently has a male who is larger than or around 5 lbs and they are willing to share the breeders name or contact info?. im basically looking for as much info on the variations as possible, since this info is not available online. thanks- jamestarpey@live.com
