Ken, Like you, I got back into the hobby about four years back. Ijumped on the four strokes, mainly because my first plane on return wasa Rupert's Dad from a build article and plans from RC Model World Magazine. It called for a 52 to 56 Four stroke so Igot busy on Ebay and picked a Magnum 52. Turns out I needed about 6 oz to balance it, so Ifound a Magnum 70 that happened to weight about 6 0z more than the 52. A lot of water has gone under the bridge since then. I now own something like 14 four stroke and a couple 2 stroke engines. The 2 strokes don't see much if any air time. The four stroke don't whine, the pull strong on a big prop, and are easy on fuel. Not much else to ask for.

Welcome back to the hobby, There is a steep catch-up curve. I'm not sure I've got to the top of it yet. It keeps the excitement going thought.
