Get the longest bow you are comfortable with, at minimum 58 inches.
The short bows are cool, but there's a reason why not a lot of them were made.
Longer recurves are a lot more forgiving and comfortable, not as long as a traditional longbows, 62 inches is about as long as I like in a recurve.
More limb movement and less hand shock, and no finger pinch.
The super mag was neet but not a bow to start with, to hard to shoot, everyone I knew that got one gave up, the people who could shoot it, could already shoot a bow, and we're willing to put up with the pain and the lack of comfort, (finger pinch, elbow pain, wrist and hand pain from the shock, and I always got a pain in the top of my right shoulder) JMO.
As for hunting, not sure of the regs in Ireland, but you don't need 70 pounds to hunt, here (Ohio) 40 will pass, and I hear someone I know got a shoot through on a nice doe with a 20 and a good sharp broadhead.
Why not just use the samik? I've shot them, decent bows, get some grizzly broadheads and sling some wood.
Judo points are great, and get a fletching jig, a single will work, look up a YouTube vid and make some arrows, it's cheaper, and bipasses all the or lack of selection.
I'm betting 3 rivers will ship to Ireland.
If it has to be a bear, the Kodiak Hunter(60 inch) is a great bow, only bear bow I regret selling, I've had a bunch, I do have a nice bearcat still that shoots great.
A Kodiak magnum (52 inch) for fishing, otherwise can't stand it, to harsh, but good in a canoe.
I guess if I had to say what's the most important part of shooting a traditional bow, after reading my post again, comfort, if the bow is harsh, or hand shoky (70s and 80s black widow, the short ones) or any short bow, kind of, comfort is up there.
Learning to shoot, and I don't mean just proper technique, it is important, but not the end all, but shooting enough that it's like pushing in a clutch when you hit the brakes, comforts important
If you think it's going to hurt every time you draw the bow, it'll suck, and you won't do it. Learning to shoot is uncomfortable anyway, all the muscle pain from shooting for hours, the blisters and string slaps on your forearm, the pain in your neck and back from the hours you'll spend looking for arrows in a cut grass yard.
Bright fletches to start, and at least one always. The bent stance and the canted hold on the bow are for comfort, ease of pull, and movement, but still, uncomfortable at first.
Good luck,
