Back to barrows? What else?

Well i've got around 17.5M cash right now, and i went to barrows a few days ago and make about 5M in one night, i'm trying to afford a dfs + whip (probably at least 22-23M for both). I'm level 78 slayer and far off 79 and i've gotten bored with it now, just plain boring. I'm wanting to go back to barrows and make more money for that DFS and whip and to do slayer again after a break like that, but i'm not sure if i'll waste money, i didn't last time apart from the fact that i bought a crystal bow and degraded it (big mistake) so i wasted 1M... So should i go back to barrows which would include re-buying all the gear etc. which isn't that much of a problem... So back to barrows which i find fun or just do something else to make like 5-6M? I have no idea, reply please, I'm kind of 50/50.

Stats:
90 attack
91 str
75 defence (It may raise at barrows (20K exp off 76 and will cb me i think) but my friend thinks i should keep it at 75 because it's good?)
5 summoning (Accident)
89 hp
92 mage
86 range

Yeah you get it, the only other skills worth mentioning are the 78 slayer and like 72 wcing...

Thanks.

 

Barrows is actually very helpful. After you buy the gear, it pays for itself through runes and such.

 

Yea, i'm doing it ATM, bought 120 P pots gonna see how much i make after all of em.

 

If you have guthans, use the ppot only method. Bring maybe 3 food and 12 ppots+etc.

 

Barrows is really fun, and will make you a lot of money. Make sure you take Guthans because it will be very helpful in tunnels.

 

Here's a hint: if you want fast mils, like 1.5m+ per hour, go to puro puro. I swear, all you have to do is run back and forth and catch implings, which are worth 20k-400k, and are very easy to obtain. I made 25m in a week doing this.

 

Yes i'm doing that ATM, full guthans and black salamander, works wonders with 92 mage. I safe Veracs and guthans, pray for dharoks, karils and ahrims and don't pray for Torags as he rarely hits even with 75 def. I bring 8 sharks and 12 p pots, just a bitch when veracs is my tunnel because i can't safe him at all and he hits through prayer and sometimes i have little food so yeah. Anyway just made 650K in little less than an hour. Gonna make a log actually.
