It is IMO fairly simple nevertheless you will see advocates for 2,3, & 4♥. You have essentially a 9 loser hand (I refuse to count more than 1♥ loser) so using the losing trick count method of evaluation you see that partner needs a 5 loser hand to make game a reasonable value so I am inclined to just bid 2♥ and leave the decision to partner. I am also ready to sell out to any number of ♠ as 5♥x does not rate to be a winning decision.
