Jeez, Sonny, it's a very pretty hand, but it's still an inside straight you're chasing. As Maverick used to say, my old grand pappy used to say to me never chase an inside straight. So in my mind you created your own problem by being in the hand at all, or if you really wanted to play it, draw for something else, if you hit say AA the laydown is easy.
The reason draw became less popular is that played properly there is hardly any action. Maxims such as never change more than 3 regardless of house rules and then only on a pair, were widely held as correct play so there was too much folding. That is why stripped deck variants became more popular. Its why people invented odd ball things like 4 card straights and flushes and skip straights.
So, just to make matters worse, in some stripped deck variants the odds change and a straight beats a flush, so you would have won! You're not comforted by that are you
Just a matter of interest, I don't play there any more, neither do our US colleagues, but the B2B network has some fun stripped deck games and games with the 4 card hands.
