Itinerary: What railpasses should I use for Europe & Great Britain?

Now that the lads and I have a decent idea of where I’m traveling, what passes will I use to get there and around?

We’re thinking that for a 4-month trip (August-November), with stops in just about every country in Europe, this combo of passes should work pretty well for a 25-year-old backpacking scribbler:

Eurail Youth Flexipass (15 days rail travel in 2 months)
* Austria, Belgium, Denmark, Finland, France, Germany, Greece, Holland, Hungary, Italy, Luxembourg, Norway, Portugal, Republic of Ireland, Spain, Sweden and Switzerland.

BritRail Flexi Youth (15 days rail travel days in 2 months)
* Scotland, England, Wales, N. Ireland

European East Pass (15 days rail travel in 1 month)
* Czech Republic, Hungary, Poland, Slovakia and Austria

Balkan Flexipass 10 days rail travel in 1 month)
* Bulgaria, Greece, Yugoslavia, Montenegro, Serbia, Turkey and F.Y.R.O.M.
That’s what we’re thinking so far, and this is also a good year to send me. I ain’t getting any younger after all, and next year I don’t apply for the under-26er discounts.
It’s amazing all the combos you can pull off with these things, too. There are so many different ways to piece together passes and point-to-point tickets. Lots of options – but lots of possibilities.
