High Country Excalibur???

I bought a few bows from a pawn shop, a buckmaster something or other, a martin cougar, and a high country excalibur. I like to tinker and shoot different bows with different set ups. I am getting curious about the high counrty bow. It has a 29" draw, the draw weight is 65lbs. It needs a new string, and from talking with my pro shop I don't think you can adjust the draw length on the cam module. I have shot the bow three times from 10 yds, the draw was smooth and it achored firmly. The 3 arrows I shot, I could wrap my hand around all three shafts so they were at least grouped. I was wondering if anyone out there has had any experience with the High Country brand. From what I've heard and gathered on the internet its a somewhat credable company that has some quality products on the market. Has anyone shot a High Country and if so what did you have on the bow? I just need a jumping off point on this bow, and those of you who like to work on and maintainence your own bows how would you go about getting the best outta this bow. I thihk its around 10 years old (probably older) but it I think with some work this bow could be my everyday bow come this fall.
Just wanted to say thanks to all you guys, everytime I post in here I get great suggestions and feedback! Hope your off seasons are going well, good luck to everyone come this fall!
