What job would you take

[big a]

Both of these job are two different trades in construction. With both jobs I feel I would be starting low enough that I would be moving up the pay scale at around the same rate. Just with job A as the company advances there would be more need for office positions where as job B there is not. The work part of both jobs I enjoy it is just that with job A there is a much high chance of having to travel. I guess it is just the chance that A could turn into something big that I am getting hung up on. Either way thanks for all the advice and for confirm everything I was leaning toward.
