Quoted from waltrr:

I guess it's really up to you as to what you like. Woodrails have so many different features from one pin to another and also year to year
Gobble holes hate em or don't mind them (nobody loves em) or what about Drop targets. Maybe you do or don't like roto targets and how about animation? There's so many different choices. Balls A Poppin, Jonnyo loves it,I for one couldn't get rid of my Balls A Poppin fast enough. Different strokes for different folks, so you need to choose, especially if you're only going for one. Ha ha, they're like potato chips. Bet you can't eat (buy) just one
I still have about 50 woodrails I've kept through the years. Lots of them are listed in my "collection". Do your research, play a few and make up your own mind. What one person likes, another might not. I rotate woodrails in my gameroom from time to time, but there are a few that never seem to leave. One is Kewpie Doll another is Sittin Pretty and my Knockout will always be up. One with Gobbles, one with Roto and one with the fantastic animation and an awesome backglass.
I wish you were closer, you're welcome here to play some. Or if you're ever by Vegas, stop in Tims place, there should be lots of them there.
Good luck on your search
