Obviously anyone can say this but im in same situation. You can get slow xp worry about cash or just go train something like rock crabs, experiments, or something. Just go kill fleshcrawlers...or go do slayer
TzHaars might take a bit longer to kill, but they are good cash, and they have safespots. If not, just go to rock crabs with iron knives. You won't make cash but the XP is really good.
UHM, I wouldn't go tzhaars you'd be wasting too many arrows/kill and the exp just isn't worth it, train at experiments/crabs till 61+ for rcbow and use moth bolts at tzhaars.
If you want to make money, blue dragons in the Yannile dungeon are always better than TzHaars imo. Might be a bit harder with a lower ranged level, but you'll still profit ^^
