The make up of a National squad

So with a lot of selection policies recently being questioned I was wondering what you, as an international rugby fan, look for in the make up of an international squad like the EPS. How big do you think a touring/training squad should be? How consistent should the composition of the squad be? How many players in each position do you like to see? Should it be the best 2-3 players in each position or is there some more important deciding factor? What about utility players, do they have a role? What mix of youth and experience? Do you have like for like replacements within your squad to keep a consistent gameplan viable or do you prefer to see different types of players in reserve?

This is an exercise in generalities. If you wish to use a specific squad and/or player to act as an example to make a specific point, please do, but do not moan about certain squads or managers please

A very good question,Squad ideally needs to be about 32 players in my view 3 hookers and scrum halves.Like for like is the way to go if possible props 2 loose head,2 tight head[preferably at least one who can cover both heads].Locks all should be proficent at basics,scrum ,lineout,restarts before playing wtq.
Back row specialists in all 3 positions 2 each,with 6/8 perhaps at least one utily.
7 is specialized.I prefer the Nz 5/8 system 1and 2 as opposed to Fh and Ic,players being inter changable skill set.Centre specialists,wings 4 ditto tho able
to cover centre or full back[at least one].Full backs specialists always,at least 4 good goal kickers,2starting one on the bench.
Continuity is important BUT,knowing when a player is past his sell by date no matter his pedigree is key.
IF a player is playing out of his skin at S15/HC level he should force his way into the squad.

well, I'll just be happy if we pick the best players.

Wales seem to have ditched their make up, not so much orange foundation on display these days.
